  • Patent number: 4068144
    Abstract: A modulator for the generation of uniform liquid drops over a wide bandwidth of drop rates is provided. The concave and convex surfaces of a hemispherical piezoelectric crystal are electroded, and the transducer formed thereby is seated within and bonded to the wall of a concave well in the face of a solid epoxy crystal backing. A ring gasket is placed contiguous to the ring shaped edge of the transducer, and a nozzle plate is placed in sealed relation with the ring gasket to form a liquid chamber between the plate and the transducer. The physical dimensions of the component parts of the modulator are made smaller than the half wavelength of the shortest standing acoustical wave that can be established at the highest of the operable drop frequency rates in a structure of the same material as the part in question.
